LcdMenu 2.0.0

What's new 😍

• The callback functions now contain arguments that can be used (for ItemList : index int is available at the callback execution site, for ItemInput : value string and for ItemToggle : isOn int 0 or 1).
  No need to call menu.getItemAt(menu.getCurrentPosition()) before getting the data you need from the item on callback execution, you already have what you need 😊
• Support for lists of values added. 🥳
• Added toggleBacklight function (JIC 🤷‍♂️)
• Examples no longer require Keypad, NeoTimer and IRRemote dependencies (testing is now possible just with serial)

Fixed

• Fixed CI workflow.
• Messed up versioning in PlatformIO Library manager 😪 (now has to start at 2.0.0)
  Because I abandoned the feature I was working on in 2.0.0-beta, it always shows on the top even though it's not the latest version
